## Abstract The sequence of ferroelectric phase transitions (__Pm__3Μ __m__β__P__4__mm__β__Amm__2) in BaTiO~3~ has been studied as a function of temperature (298 Kβ130 K) at a fixed pressure (3.2 GPa). The same sequence of transitions is observed as for ambient pressures, but the transition temperat
